Mixing up the sticky stuff

It's been a while since I've posted here, but finding myself in need of a little prior knowledge, I figured I'd come and tap the font of wisdom and experience (No really....) that is VFRWorld's member's list.

The Avon Azaro ST's that were fitted to my 3rd gen' when I bought it are getting less-than-legallly low on tread, so I figured it was time to buy some black stuff. Having read a few reviews, and looked up a few mileage comparisons, I ordered a pair of pilot roads from an online UK firm. Next day, I get a call:

"Hi, Mr. er..... Strobert....?" (nobody alive, it seems, can pronounce my last name)
"we dispatched your front tyre this morning, but when we came to send the rear, it turned out that it wasn't in stock. I'm just calling to see if we can find an alternative"

O.K, so it was listed on your site as in stock because...?

"Well... (long pause)... I think maybe the stock file wasn't updated. Sorry about that. We can offer you a few alternatives though. I can send you a Conti'-Motion, a Dunlop Qualifier, or a Metzeler roadtec Z6 for the same price" (all those being sold at a little more than I'd paid for the pilot roads I ordered)
"or we could send you a pilot road rear at 180/60, which should still fit your wheel"

:chairshot:

So I told him I'd call him back, and, not really wanting to go for a 180/60 (my 3rd gen' wants a 170/60 really) I looked for a few write-ups on the others he'd offered. After a bit of a look, I called him back and said, yep, send me a Metzeler rear instead.

Tempted as I was by the sticky Qualifier's, I need mine to last longer than it seems those do really. So - my question is, does anyone have any experience with mixing these two tyres?

I'm gonna end up - when they arrive, with a Michelin pilot road front, and a Metzeler Roadtec Z6 rear, and I'm beginning to wonder whether this is likely to cause compatability issues, in the form of peculiar/unpredictable/scary handling. I'm aware that Metzeler state that their rear should not be used with anything other than a Z6 front tyre, but this is because it's supposedly designed to work with the water dispersal pattern of the front tyre, so tbh I'm not all that concerned with that, as I don't do that much riding in the wet, I don't tend to push it when I do, and it does sound a little like Metzeler being happier selling two tyres rather than one.

I'm more concerned with whether the profiles of the two tyres will work well together. Any advise would be much appriciated, as obviously If it's gonna be an issue, I've gotta do summut about it before they get fitted!

 

Everything I read (according to the experts) says NEVER mix and match manufacture brands. Different profiles and tread patterns will lead to a ill handling bike. I have even read where it is said you should always install your tires in pairs. Don't put a new one with an old one.I would send back that rear for a pilot to match the front or cancel the whole order and start over,for sure. I have had 2 pair of the Metzler Z6's on two different bikes, wore like iron but would slip a little more than I liked. In mho they are not as good as the road CT2's. But maybe you can't get these on your year bike. Whatever,they should match.
